Grasses are the world’s most important plants. They are the dominant species over large parts of the earth’s land surface, a fact that is reflected in the many different words that exist for grasslands, words such as prairie, veldt, palouse, and pampas to mention just a few. As a group, grasses are of major ecological importance, as soil binders and providers of shelter and food for wild animals, both large and small. Some grasses, such as wheat, rice, corn, barley, rye, tef, and sugar cane are major sources of calories for humans and their livestock; others, primarily bamboos, are used for construction, tools, paper, and fabric. More recently, the seed catalogs that tantalize gardeners each winter have borne witness to an increasing appreciation of the aesthetic value of grasses. The Manual of Grasses for North America is designed as a successor to the classic volume by Hitchcock and Chase. It reflects current taxonomic thought and includes keys, illustrations, and distribution maps for the nearly 900 native and 400 introduced species that have been found in North America north of Mexico. In addition, it presents keys and illustrations for several species that are known only in cultivation or are of major agricultural significance, either as progenitors of bread wheat and corn or as a major threat to North American agriculture because of their ability to hybridize with crop species. The Manual is a major reference work for grasses that will retain its value for many years.

Scientific keys help identify the grasses to group, genera, and species, and an alphabetized checklist includes information on: origin (native or introduced); longevity (annual or perennial);growth season (cool or warm season); endangered status;and occurrence (by ecological zone). A glossary, literature citations, and a quick index to genera round out the book.

"The first opportunity for both the native plant enthusiast and professional botanist to tackle the difficult family--presented in such a manner that it will make identifying the grasses a pleasure!"--Paul Martin Brown, editor, North American Native Orchid Journal "A unique and important work that will assist many in identifying and appreciating an extremely important but challenging group of plants"--Paul A. Schmalzer, plant ecologist, Kennedy Space Center Grasses comprise approximately a third of the Earth's vegetative cover and, as a group, have a wider distribution than any other plant family. From wheat, rice, and sugarcane to bamboo and bermudagrass, humans have depended on grasses as sources of food, food for animals, lawns, and construction material for millennia. A Guide to Florida Grasses offers an introduction to this vital and frequently neglected plant family. This richly illustrated reference includes complete details pertaining to the identification, structure, distribution, and uses of more than 200 of the most common grasses found in Florida and nearby states. With over 500 color images--some picturing species that have never been described with a published image--correctly identifying and selecting members of this important plant family has never been easier. Environmentalists, hikers, and nature lovers can take this book into the field or enjoy it at home. A Guide to Florida Grasses will be accessible and invaluable to professional botanists, commercial landscapers, homeowners, and plant enthusiasts alike.

The Grasses and Native Plants manual is a reference manual on diseases which attack grasses, forage, native flowers, and weeds. The manual identifies various types of diseases which are known to invade these plants located throughout North, Central, and South America. The recordings include diseases caused by fungi, bacteria, viruses, viroids, phytoplasmas, and nematodes. Causal disease agents are described and illustrated in some cases and diseases and disease control measures are also discussed. A manual such as this is never finished since new reports of diseases are continuously reported.
